经过零点能校正后能位面被作了出来。
The potential energy surface with zero-point energy correction is drawn.
在作偏移处理时，一般要求偏移基准面是水平的，且偏移的零点应在激发和接收的地表。
In migration processing, we usually require that migration datum is horizontal and that zero point for migration should be on the ground surface on which shot point and receiving points lie.
另一方面，使用过零点的特有属性作为粗匹配的匹配约束，可以提高匹配速度。
In the other, we use the particular attributes of zero-crossings as constraint in coarse matching, which can improve the matching speed.
针对地震反演预处理的地震降噪问题，本文结合小波分析设计了一种过零点滤波器，对多分量地震资料进行了面波剔除研究。
In the denoising and preprocessing for seismic inversion, a zero-crossing filter is developed based on wavelet analysis to remove surface waves from the multi-component seismic data.
